By Rev. Rudolf Allers, M.D., Ph.D. This book is based on Christian philosophy and Christian morals. They supply the general trend of the reasonings, but they are not the point from which these reasonings start. All that is explained in the following chapters is based on experience. It is facts and not speculation. And these facts may, in a way, contribute to prove the general and philosophical point of view to be true and, therefore, to be the one which will be more helpful in arranging our life.
